CVE-2023-2567: Authenticated SQL Injection on Query functionality in Guardian/CMC before 22.6.3 and 23.1.0

Noroxi assessment

Priority: Monitor (action score 34/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.61% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Nozomi Networks CMC 22.6.3, 23.1.0; Nozomi Networks Guardian 22.6.3, 23.1.0.

Low priority for now. Upgrade to Nozomi Networks CMC 22.6.3, 23.1.0; Nozomi Networks Guardian 22.6.3, 23.1.0 or later.
